  }
}

I have tried using $tournament->tournament[0]->name but it is not working.

Does anyone have any advice?

Use $variable->tournament->name

Demo

<?php

$json = '{
  "tournament": {

Hi, thanks! This worked perfectly! Can I also do it for the participants as well?

John Conde Over a year ago

They will be even more nested but this should give you the idea of how to do it

cheese5505 Over a year ago

1 more question, if I have multiple participant arrays, how can I go through each one of them?

cheese5505 Over a year ago

Nevermind, found out myself. Thanks for the help! I will set your answer as the correct one when I can.
